Data Description

Sold! How do home features add up to its price tag?

Ask a home buyer to describe their dream house, and they probably won't begin with the height of the basement ceiling or the proximity to an east-west railroad. But this playground competition's dataset proves that much more influences price negotiations than the number of bedrooms or a white-picket fence.

집을 구매하려는 사람에게 그들의 꿈의 집을 설명해 보라고 해보자. 그들은 아마 지하실 천장의 높이 혹은 동-서부간 열차와의 근접성부터 말하진 않을 것이다. 그러나 이 playground 대회의 데이터셋으로 침실의 숫자 혹은 하얀색 말뚝 울타리보다 더 가격흥정에 영향력이 있는 것을 밝힌다.

With 79 explanatory variables describing (almost) every aspect of residential homes in Ames, Iowa, this competition challenges you to predict the final price of each home.

아이오와주 에임스에 잇는 주거용 집들의 모든 요소를 설명한 79개의 설명변수들로, 이 대회는 여러분이 각 집의 최종가격을 예측하길 바란다.

The potential for creative  provides a rich opportunity for fun and learning. This dataset lends itself to advanced regression techniques like random forests and gradient boosting with the popular XGBoost library. We encourage Kagglers to create benchmark code and tutorials on Kernels for community learning. Top kernels will be awarded swag prizes at the competition close. 

창의적인 feature engineering 에 대한 가능성은 즐거움과 배움에 대한 많은 기회를 제공한다. 이 데이터 셋은 랜덤 포레스트와  XGBoost library의그레디언트 부스팅같은 고급 회귀기법들에 적합하다. 우리는 캐글러들이 커뮤니티 러닝을 위해 Kernels에 벤치마크 코드와 튜토리얼을 만들기를 권장한다.
